Specification of Letters Patent.

Application filed June 10, 1905- Serial No.264,703.

To all whom it may concern.-

Be it known that we, JOHN P. ABERNATHY and JAMES W. HIETT, citizens of the United States, residing at Jonesboro, in the county of Craighead and State of Arkansas, have invented new and useful Improvements in Plow-Colters, of which the following is a specification. w. Our invention relates to improvements in plow-colters.

Objects of the invention are to provide for the effective retention in adjusted position of the colter and to carry out the same in a simple, economic, and expeditious manner; and to these ends it consists of certain structural features, substantially as hereinafter fully and specifically pointed out.

In the accompanying drawings, illustrating the preferred embodiment of our invention, Figure l is a side elevation of a portion of a plow with said invention applied thereto. Fig. 2 is a longitudinal or axial section thereof. Fig. 3 is a detached perspective view of the principal feature or part of the invention.

In the disclosure of our invention we provide the plow-beam 1 with a mortise or socket 2 to receive the colter-shank 3, provided with the usual adjusting pin-receiving apertures 4, arranged in vertical alinement one above the other. Said mortise is produced, preferably, in V form, with the taper presented downward. To the lower side and the top side of the beam 1 are suitably secured preferably malleable metal plates 5 6, respectively, with their respective openings 5 a 6 registering with the upper end and the lower end of the mortise 2 in the beam 1, the lower plate 5 having its opening 5" just of the requisite dimensions for the passage therethrough of the coltershank. The plate 6 is provided around the upper edge of its opening 6* with an upstanding preferably box-like flange 6*, the lateral walls or portions of which are equipped with registering holes 6. Through any two alining openings or holes 6 may be inserted the adjusting and securing bolt or pin 7, the same also being inserted through any one of the adjusting-holes 4 in the colter-shank 3, as done in supporting and effecting the adjustment of the colter, as readily understood. This arrangement provides for the vertical adjustment or raising and lowering of said colter, as well as for varying the an le or inclination of the position thereof, as wi 1 also be readily appreciated. The preferable way of securing the plates 5 and 6 upon the beam 1 is by passing headed and nut-equipped bolts 8 through the beam and plates, as shown, while through the adjusting and securing bolt or pin 7 may, as disclosed, be inserted transversely a strip of leather or thong 7 for its retension from accidental displacement.

A spring-lock 9, comprising a more or less resilient bar or member 9*, the greater portion or length thereof being produced upon a practically right line, said right-lined portion being extended into an angular terminal 9 and a curved or arouate terminal 9 respectively. The former is relatively thickened and efiective for seating in the socket or mortise 2 between the colter-shank and the forward or rear wall of said mortise, according to its disposition with relation thereto for impingement upon said parts. To the upper end curved terminal 9 of the member 9 is pivoted a manually-actuated dog or lever member 10, said terminal being formed, preferably, into an eye 9, upon the practically concaved side of said terminal, thus removing said eye out of the plane of said member for a purpose which is apparent. Said dog or lever member 10 has an inner end lateral or right-angled prolongation or extension 9 which is bifurcated, and between the branches or limbs of which'is received the eye 9 of the member 9 and through registering apertures formed in said branches and said eye is inserted and clenched or riveted a rivet 9 constituting a pivot for said dog or lever member and whereby a cam or eccentric action of the latter is obtained as it is actuated. The dog or lever member 10 has a practically right-lined surface or edge 10 effective for presentation to and engagement with the edge of the-colter-shank, said engaging edge 1O standing in a plane eccentric to the 'vot of said dog or lever member, uniting witli the foregoing to secure the aforesaid eccentric or cam action, consequently to render effective the binding or clamping action of the lever member or dog upon the colter shank or standard. The handle of the dog or lever I terminal or lower end of the spring-bar member 9 inserted clear downinto the bottom of the colter-shank-receiving mortise, either in front or in rear of said shank, according to the adjustment of the latter, and by then suitably manipulating the lever member or dog it is apparent that the latter may be brought forciblyinto contact with said coltershank and these be held or locked by its eccentric or cam action securely in place,

thus providing for eflectively holding the' dog or lever member having a lateral bifurcated terminal receiving said eye, and a clenched pivot bolt or rivet for effecting connection between said bar member and said dog or lever member.

3. In a plow, the combination of a coltershank with the carrying-beam therefor having a mortise receiving said shank, means for securing in place and efiecting the adjustment of said shank in said mortise, and a locking contrivance for said colter-shank comprising a resilient bar or member insertible in said mortise and a dog or lever member hav ing an eccentric or cam connection with the latter, and eflective for securing a binding or clamping action thereof upon said coltershank.

In testimony whereof we afiix our signatures inpresence of two subscribing witnesses.
